How long would it take to fill the Grand Canyon up with pee?

Filling the Grand Canyon with pee would take an astronomically long time, estimated around 800,000 years, even if all 8 billion people on Earth peed into it continuously, because the canyon's immense volume (trillions of gallons) vastly exceeds daily human output (about 4 billion gallons/day from everyone combined). Factors like evaporation and the canyon's shape (never truly "filling" like a bowl) further complicate the idea, but the core answer is hundreds of thousands of years.
